The Influence of Filter-Compensating Devices on the Technical and Economic Indicators of Transformer Substations

The study of the energy consumption mode of the transformer substation in the case of a decline in the quality of electrical energy was carried out. It was found that the current flowing in the line is significantly less than the nominal one, which indicates that the line is underloaded. Economic losses caused by a decline in the quality of electric energy for the actual and calculated regimes for ten years, taking into account the increase in the cost of electric energy, are calculated. The installation of filter-compensating devices on the busbars of the transformer substation in order to improve the quality of electrical energy is proposed. The economic feasibility of the proposed technical measures using discounted estimates methods was determined.
